This code could be made a little shorter by relying on Reflection to do the classloading and compilation. We intentionally do it here to give us a chance to provide error messages that are specific to not being able to find the main class the user wants to run. This may be a little silly, since it results in code duplication just to provide debug messages in a place where very little is actually likely to go wrong, but there you have it....
